Leeches

I hope someone can help me as we are losing a fish a day and i was wondering if it has some thing to do with the leeches that we have recently found living in our pond as we have never lost so many in such a short space of time before and i am so attached to my fish also we have newts and frogs and toads and this year we have had no tadpoles at all !! ,if it is the leeches how do we get rid of them?

If they're killing your fish you'll see them attached to the fish before the death. It's not an instant death.

Newts are more likely to be responsible for lack of taddies. They like frogspawn. Since the newts moved in we have no frogs to speak of. I feel pleased to have greacrested newts but I'd like to see the frogs again

the fish are just floating each morning and it not the age of them as it has ranged from the oldies in the pond to last years hatchlings and we have tadpoles every year even with the newts but this year not one and we didnt have leeches last year so i am stumped as to what to do

I can,t imagine its anything to do with the leeches,we have had fish for 30 years and leeches are frequently seen along with the usual pond creatures and have never caused a problem.

As your fish are floating each morning,it could be something poisonous has found its way into the pond water,I would try emptying the pond by about two thirds and then refilling.It may be worth buying some pond treament as well.

It could also be a fungal infection of the actual fish,do they have any unusual lesions on the scales?
